E-Motive Performance & Auto Repair Off-Road & 4X4 Gearing in Mertztown
When it comes to off-road capability, few upgrades matter more than the right gearing. Whether you’re crawling over boulders, navigating steep inclines, or just trying to keep your lifted rig smooth on the street, your drivetrain needs to be dialed in. At E-Motive Performance & Auto Repair, we specialize in off-road and 4×4 gearing that delivers the torque, traction, and control serious drivers demand.
We serve Jeep owners, lifted truck enthusiasts, and SUV drivers seeking genuine performance, not just appearance. From axle re-gears to locking differentials, we install the components that match your tire size, terrain, and driving style.
Build Your Drivetrain Around the Trail
Proper gearing transforms how your 4×4 behaves on and off the road. It can be the difference between stalling on a climb or crawling up with confidence. We guide you through the best options for your setup, your driving goals, and your vehicle’s unique platform.
Ring & Pinion Gear Swaps
Swapping to the correct gear ratio is essential when upgrading to larger tires or tackling demanding terrain. Without the right gears, your off-road vehicle can feel sluggish, overworked, or inefficient, especially in low-speed conditions.
- Common gear upgrades: 4.10, 4.56, 4.88, and 5.13
- Restores throttle response and acceleration with oversized tires
- Reduces engine strain and improves towing and crawling capability
- Ideal for lifted Jeeps, trucks, and SUV platforms
Locker Installation
Locking differentials are a game-changer when one wheel loses traction. Whether you’re crawling over rocks, slogging through mud, or recovering on uneven terrain, lockers provide equal power to both wheels for superior control.
- Available for front and rear axles
- Compatible with most aftermarket axles and OE housings
- Maximizes traction in off-camber and loose terrain situations
- Trusted setups for Wranglers, Gladiators, Tacomas, and more
Axle Re-Gears
Axle re-gearing goes beyond just the ring and pinion; it ensures your entire drivetrain is up to the task of handling larger tires and increased trail loads. Without proper axle ratios, you risk premature wear and underperformance.
- Boosts fuel economy and throttle feel with large tires
- Improves towing capacity and off-road torque
- Supports driveline upgrades for lifted and loaded builds
- Critical for maintaining power delivery in 4×4 setups
Transfer Case & 4WD Optimization
Your transfer case is the unsung hero of your 4×4 system, splitting torque and enabling low-range functionality. When you upgrade gears or tires, your transfer case must be recalibrated or upgraded to maintain driveline harmony.
- Low-range upgrades for extreme crawling or towing
- Syncs with gear ratio and tire size changes
- Smooth engagement in both high and low 4WD modes
- Ideal for serious off-roaders and weekend warriors alike
